Do electronic repair businesses have to disclose their actions used to repair the product with the customer? -

I took my xbox 360 into a local repair center about a week ago. I went in yesterday and when I asked what was wrong with it? they replied I can t tell you, but it was bad. Right away, red flags went off. The original estimate was $40-$140. The final price was $135. I know in auto repair, they are required to return any broken parts to the customer upon request. Do these same laws apply to electronic places? Do they need to tell me what they did to it? On the initial sheet they gave me where I filled out what was wrong with it (RRoD), at the bottom there is a section to be filled out by employees about what they did, but this section was left blank. The store owner signed this sheet.Thoughts about what I should do?*Note: I have already paid the $135, but I plan to go back in tomorrow and raise some hell.

They have to quote for the work before they carry it out. Unless you authorise payment, they have to return it to you in the condition that you gave it to them (minus a fee for diagnosis if it was agreed when you booked it in). So therefore, you can demand that they tell you what was wrong and what they re doing before you authorise them to carry out any work. However, if you have already paid up, unless you can actively prove that they did not fix the problem, or carried out unnecessary work, I think you re stuck (aside from the possibility of goodwill from the company if they recognise their employees did wrong).
